公路设计中模拟行车任意车速控制技术的实时实现

Technique Realization for Controlling Speed in Simulated Driving

OpenGL技术是公路设计中生成道路实时三维动画模拟的主要方法之一。在介绍了数字地面模型和三维道路模型的基础上,给出了三雏道路动画实现的方法;并针对车辆实际行驶中,驾驶员凭直觉调整车速的问题,提出了任意车速实时控制的技术,来模拟更真实的视觉效果。通过编程验证,证明了这种处理技术的可行性,文章还给出了部分Delphi编程的源代码。

OpenCL technique is one of the main methods for creating the real-time road animation.In this paper,the basic conceptions of digital terrain model and 3D highway modeling were introduced and the methods of making 3D road animation were presented.Then aimed at the issue of changing speed in actual driving,the paper worked out the technology of real-time speed-control,using which technology can get better visual effect.It proved the feasibility and rationality by programming,and at last,some source codes were given using Delphi.
